BenQ AK700ST

Manufacturer: BenQ

The BenQ AK700ST is a 4K laser projector designed for high-resolution large-screen projection, capable of displaying images up to 200″ in size. It uses a laser light source rated for up to 20000 hours in eco mode, making long-term reliability a practical consideration. The unit has a relatively compact footprint for its category, measuring 300 mm wide, 230 mm deep, and 110 mm tall, with a weight of 3400 g.

On the optical side, the BenQ AK700ST delivers 4000 ANSI lumens of brightness and supports 10-bit color depth along with HDR10, while Dolby Vision and HDR10+ are not supported. Motorized focus and zoom are both included, though manual focus is absent. For connectivity, the projector offers 2 HDMI ports and 3 USB ports, but lacks Wi-Fi, Bluetooth, and Ethernet. A single built-in speaker with 10W audio output and a 3.5 mm headphone jack are present, though there are no stereo speakers, Dolby Atmos, or lens shift in either axis. Operating noise is rated at 32 dB, dropping to 29 dB in eco mode, and the unit carries a 3-year warranty.

Pros
  • 4K output resolution paired with 4000 ANSI lumens provides a high-brightness large-format image, with support for screens up to 200″
  • Laser light source rated at 20000 hours in eco mode reduces the need for lamp replacements over extended use
  • Both motorized focus and motorized zoom are included, allowing lens adjustments without manual intervention
  • 10-bit color depth and HDR10 support enable a wider tonal range in compatible content
  • Operating noise drops to 29 dB in eco mode, which is relatively unobtrusive for a projector at this brightness level
  • Backed by a 3-year warranty, offering a reasonable coverage period for a projection device
Cons
  • No wireless connectivity of any kind — Wi-Fi, Bluetooth, AirPlay, Chromecast, and Miracast are all absent
  • No lens shift in either vertical or horizontal axis limits placement flexibility and installation options
  • 3D content display with glasses is not supported
  • No Ethernet port, restricting network-based use cases entirely
  • The built-in speaker is a single 10W mono unit with no stereo capability and no Dolby Atmos support
  • No smart TV platform is built in, so content access depends entirely on external source devices
Who is this for?

This projector is well suited to users who need a large-screen 4K projection setup in a controlled environment, such as a dedicated home cinema room or a professional presentation space. With 4000 ANSI lumens and a maximum image size of 200″, it works well for venues where screen size and brightness matter. The laser light source with a 20000-hour eco-mode rating makes it a practical choice for settings where long-term, low-maintenance operation is a priority. The motorized focus and zoom also make it suitable for fixed installations where remote lens adjustment is preferred over manual handling.

Who is this NOT for?

This projector is not a good fit for users who rely on wireless streaming or smart platform access, as it lacks Wi-Fi, Bluetooth, AirPlay, Chromecast, Miracast, and any built-in smart TV functionality — all content must come from a directly connected source. It is also poorly suited to flexible or improvised installation scenarios, since the absence of both vertical and horizontal lens shift means precise physical placement is essential to achieve a properly aligned image. Users who need 3D content playback or advanced audio formats like Dolby Atmos will also find this unit lacking in those areas.

Final Verdict

The BenQ AK700ST is a capable 4K laser projector built around a clear set of priorities: high brightness, large-screen output, and long-term reliability through its laser light source rated at 20000 hours in eco mode. Its 4000 ANSI lumens, motorized optics, and 10-bit HDR10 support make it a solid choice for fixed, dedicated projection environments where image scale and sustained performance matter. That said, the lack of wireless connectivity, lens shift, and smart platform support means it demands a well-planned installation and relies entirely on external source devices. For users whose setup aligns with those requirements, the BenQ AK700ST delivers a focused and dependable projection experience.
